I recommended your story but ……..
There is way more that needs to be discussed. Gradually we are adjusting to the coming end of “Might makes Right.” Some where some how White Men gathered up great power to themselves and fought among themselves to determine the distribution of the Worlds Wealth and Power. They did this through force of arms. The costs were appalling and the Ruling Elite White Men created an uneasy peace. In this process they did have to give up some Wealth and Power to the Ruling Elite Asian Men and some tiny bits to Ruling Elite African Men.
“Might makes Right” did not completely die just the weapons changed from Physical the Fiscal. The weapon that ended the Cold War was Economic Strength.
I am not sure if the end of legal slavery was some moral awakening or more likely a tool in the internal struggles of the competing Ruling Elite White Men. Those who carried the narrative forward of Justice for African Slaves have carried the day.
We still only have the rights we can defend. It may be your right but you still can be oppressed, suppressed and killed if you don’t have the power to defend.
I think many Elite White Politicians mostly support equal treatment because it supports their Electoral Goals.
In a democracy the faction with the greatest numbers will most likely benefit the most. The only counter to that is for the minority faction to be more effective. Since the minority won in this last election then they must have been more effective. This could be because of a historical advantage of having a head start, their elite were more elite than the majority’s elite.
If you were raise with a better diet, heath care, education, family situation, and finances you might be a bit smarter, stronger, quicker and have better connections than the next guy.
How do you propose to convince more people to give up their advantages? How superior will need be your majority to overcome their technical advantages. If the White Working class wakes up and comes around, they can be just as effectively disenfranchised as other disadvantaged groups.
